Oh how much time is spent getting a group and littering the underside of things on your desk with snot balls.
Necro's don't need them. Necro's will make the backside and undersides of things clean again. You will not remember /lfg.
Only downside, as I said, is their evil lore and faction problems and the large amount of spells and tactics you must learn. There're places in the game where levelling them is very easy while other places are not.
It's a class that takes time but has the greatest potential, if you're friendly to their solo-nature.
If you like groups, I'd suggest a monk. Maybe not the fastest, but much endurance. What goes unstated is what classes are best at MAX level. At max level, it's typically in this order: enchanter, cleric, monk, rogue, warrior, wizard. But moreso, monks have good armor class with cheap armor or even no armor. You can kill good even without weapons. They have feign death if you want afk. They can do a little bit of tanking/dps/pulling. Experience rate is good. Good lore. Great grouper.
Minus the Necro and Monk, I'd recommend hte Magician, even though their endurance is questionable. The reason is they're comfortable to level. Players like em because they can sit lazily and order their pet to kill. They can even do good in groups. Their pet and their dps spells are good. Unlike the Necro, they're not swamped in spells/abilities and don't rely on dots. The caveat is they don't group well in every situation, given any melee will gain aggroes from the pet, thus requiring heals.
These're the least popular and the hardest to find:
Paladin
Shadowknight
Bard
Ranger
Avoid them unless you have a primal urge like myself. In that case, nobody needs to tell you. You won't ask. I played the ranger before there were forums, or before I was ever aware forums for EQ existed. This was long ago, in March 1999.
You might refer to the class popularity chart and the post I made about it here (circa 2011-12):
